Hello,
I am just learning the ropes of Square API. I am currently using google pay api and then sending the token to the backend using square API. I am a bit lost on the topic of applying tax correctly. I am from Canada. From my current understanding, I only charge tax on canadian buyers (and also based on their province), else I don't charge tax. (I don't have a nexus in US)
Now to figure out which province they are from, I believe I need to get it from the google token, but I can't figure out how. I think I can get it from client side and I guess I could send it to server, but you can't trust anything sent from the client side unless its cryptographically signed like the google token from google pay. So I was thinking to decode it and get the billing address from there, but I can't figure out how.
Does anyone have any advice for this?
